Regarding dimples on an airplane. The Mythbuster did a program were they compare the fuel mileage of a smooth skin car with that of a dimpled skin car. The dimpled skin car got 10% better mileage.

HOWEVER Dimples on an airplane DO NOT improve mileage or anything else. After the show I was tempted to "dimple" my plane but thought to ask my nephew about it. He is an aerospace engineer and works at the wind tunnel at Langley for NASA. He is a true rocket scientist.

He explained to me in terms I could not begin to understand that the airflow around a car (and a golf ball) is basically turbulent and the air flow across an airplane is basicallty laminar. The effects of the dimples is totally different on the laminar airflow.

I did not dimple my airplane.

I know just enough about this to be dangerous. I hope someone with true knowledge can expand upon the matter.

Good wife, good friends & a Cessna 150. Life is good.
